J. H. IRWIN' OIL STOVE.

Patented Feb. 14,1882.

UNITED STATEs PATENT OFFICE.

JOHN H. IRWIN, OF MORTON, PENNSYLVANIAQ OlL-STOVE.

SPECIFICATION forming part of Letterslatent No. 253,607, dated February14, 1882.

Application filed September 152, 1881.

To all whom it may concern:

Be it known that I, JOHN H. IRWIN, of Morton, in the county of Delawareand State of Pennsylvania, have invented certain new and usefulImprovements in Oil-Stoves, of which the following is a full, clear, andexact description, reference being had to the accompanyin g drawings andthe letters marked thereon.

My invention relates especially to that class of stoves, both forcooking and heating purposes, wherein hydrocarbon oils are used as fuel;and has for its object the production of a device which will be safe inuse, andin which, in case of ignition of the contents of the oil-pot,the flame of the burners will be instantly extinguished, my presentinvention embodying the same principle as heretofore set forth in anapplication for patent for improvement in lampburners filed by me August27, 1881.

To accomplish the desired results my invention involves certain noveland useful combinations or arrangements of parts and peculiarities ofconstruction and operation, all of which will be hereinafter first fullydescribed, and then pointed out in the claims.

In the drawings, Figure l. is an elevation and partial section of astove, showing the arrangement of the various parts embraced in myinvention; and Fig. 2 is a plan view of the top of the oil-pot.

Like letters of reference, wherever they occur, indicate correspondingparts in both the figures. 7

A is a metal basin, supported by suitable legs, a, the same elevatingthe basin but slightly from the floor, table, or other object upon whichit is placed. Said basin is of such size and shape as to permit a stoveto stand therein,

. leaving a narrow space between the basin and the oil-pot. The objectof this device is to catch and retain any oil that by accident dripsfrom the stove or that is spilled in filling the same; and in case thecontents of the oil-pot takes fire and flows over, it will he caught bythe basin, and communication of fire to the support of the stove andrunning of the burning fluid upon surrounding objects will be prevented.

B is the base of the stove, in which is located the oil-pot 0, formed ofany suitable material. C is the top of the oil-pot, provided at D (Nomodel.)

with an elongated perform ionex tending across the oil-pot from side toside. In the stove represented in thedrawings perforation l) is shown asprovided with a collar, E, therearound, ex- L tending up into the airchamber or conduit F. Fitting over perforation D, upon the top of collarE, is a trap, G, hinged at one side, as shown.

B are the burners, the same being of any approved pattern. Upon theinterior of the oil-pot, attached to the top thereof and surrounding thewick-tubes, is a chamber, H, having its bottom H raised but a slightdistance from the bottom of the oil-pot. The center of bottom H isperforated with one or more openings,l,ofsuflicient capacity to supplytherequisite quantity ofoil to the burners. Over perforation I is aplate, J, extending beyond the perforation in each direction. This plateis held in position above said perforation by means of rivets i, or inany other suitable manner, the plate being so placed as to leave justsuflicient opening between plate I and bottom H to permit the passage ofoil to the burners, but in case of accident to substantially prevent thepassage of fire.

L is a suitable filler for supplying oil to the oil-pot, and K are theburner-cones, through which the flame passes.

The construction of the upper portion of the stove may be of any style,that shown in the drawings being my approved tubular form.

It will be seen that by the method employed by me for supplying oil tothe wicks but a very small quantity of fluid will come in actual contacttherewith at one time, the greater portion of that contained in theoil-pot being separated from-the burners by means of the tight wallsofcbamber H and flowing to the wicks through a contracted tortuouschannel. In case the burners'become heated or the flame is commu-'nicated to the oil or vapor around the wickcomes ignited by a reversalof theflame, and the stove is of the ordinary construction, anexplosion, attended with the usually serious results, must follow, asthere is no provision made for relieving the pressure generated in theoilpot by such ignition. To obviate any serious results from suchexplosion is the object of my invention.

In my improved stove,if, by accident, flame passes to the mixture in theoil-pot, igniting it and causing explosion, the hinged trap G will beraised, allowing free escape of the products of combustion into theair-conduit to the burners, and as the trap is hinged upon the side ofopening D toward the fresh-air supply, this will be substantially cutoft, and the products must find vent toward the burners and through theslot in the burner-cones, doing no further damage than to instantlyextinguish the flame.

Should any oil remain in the oil-pot and take fire, it will be deprivedof air to. support combustion by the falling of the trapto its place,after relieving the oil-pot of pressure, extinguishing the flame at thatpoint.

Having now' fully described my invention, what I claim as new therein,anddesire to se cure by Letters Patent, is-

1. In a hydrocarbon-oil-burning stove of the I character, hereinspecified, an opening in the oil-pot having communication with the feedair-conduit to the burners, said opening being provided with a trap,hinged at one side, and

adapted andarranged to substantially close,

the feed air-conduit and direct products of combustion escaping from theoil-pot toward the burnersin case of explosion, substantially as shownand described.

2. In a hydrocarbon-oil-burning stove of the character herein specified,the combination, with the oil-pot, of outlet D, trap G, and air-conduitF, substantially as shown and described.

3. In ahydrocarbonoil-burning stove, an oilpot having a chambersurrounding theWvicktubes, and extending nearly to the bottom of theoil-pot, an opening for the passage of the fluid to the wicks beinglocated in the bottom of said chamber, with a plate placed thereaboveand secured to the bottom of said chamber, substantially as shown anddescribed.

at. In a hydrocarbonoil-burning stove, the combination, with theoil-pot, of jacket H, the same being perforated at bottom, and having aplate,-I, located therein, substantially as and for the usesand'purposesshown and described.

In testimony that I claim the foregoing I have hereunto set my hand inthe presence of two witnesses.

JOHN H. IRWIN.
